CX_SPAN_DATE - Arithmetik

Arithmetik

Die folgenden Übersichten zeigen die mathematischen Operatoren und die Operanden mit denen eine Datumsperiode verknüpft werden kann.

Addition

CX_SPAN_DATE + INTEGER = CX_SPAN_DATE ->
12.5.96 - 14.5.96 + 1 = 13.5.96 - 15.5.96  
12.5.96 - 14.5.96 + -1 = 11.5.96 - 13.5.96  

CX_SPAN_DATE + CX_NUMERIC = CX_SPAN_DATE ->
12.5.96 - 14.5.96 + 1 = 13.5.96 - 15.5.96  
12.5.96 - 14.5.96 + -1 = 11.5.96 - 13.5.96  

CX_SPAN_DATE + CX_VALUE = CX_SPAN_DATE ->
12.5.96 - 14.5.96
